I do not argue that markets go up as well as down -- if you have read some of my older posts, it is not what the market is doing so much as how it is doing it. I have been trading the markets for a long time and as an old tape trader the trading patterns I have been seeing in this rally are very abnormal and like nothing I have seen before. The Greenspan Gambit explanation is the only one that fits what Greenspan (and Bernanke) have said, is totally logical from an economic point of view, explains the abnormal trading patterns, and has been accurately predictive of what the market was going to do.
That has been good enough for me, so I will stick with it without apologies.
